Application filed March 23, 1910.

To all whom Lt may concern:

Be it known that I, MIKE BANowETZ, a citizen of the United States,residing at Coffeyville, in the county of Montgomery and State ofKansas, have invented certain new and useful Improvements inLawn-Mowers, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to lawn-mowers and hasfor its object to provide alawn-mower so constructed and arranged that it will be strong anddurable and will effectively carry on the work which it performs.

The invention has further for its object to provide an improvedlawn-mower having its operating mechanism so constructed and arrangedthat it will occupy little space and at the same time will furnisheffective driving power for the cutters.

With these and other objects in view, the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

Referring to the accompanying drawings: Figure 1 is a side view of alawn-mower con structed in accordance with this invention. Fig. 2 is aview similar to Fig. 1 showing a portion of the operating mechanismuncovered. Fig. 3 is a plan view of the lawnmower. Fig. 4 is an enlargeddetail view partly in horizontal section and broken away of a portion ofthe operating mechanism.

In the construction of this invention, a pair of toothed driving wheels1 are mounted upon a shaft 2, said driving wheels 1 being each formed ofa disk-shaped plate 4 fastened to the shaft 2 and having an annularflange 5 with teeth 5 on its periphery. A disk-shaped plate 6 is locatedon the outside of the wheel 1 and within its periphery and forms withthe flange wheel 1 a casing. The plate 6 is formed with an extension 7having a tubular projection 8 and tubular projection 9. The extensions 7are connected together and braced by means of rods 10.

The cutting knives 11 of the lawn-mower are mounted on a shaft 12 whichhas its bearings in the projection 9 on each of the extension plates 7.The shaft 12 is connected with the driving wheels 1 by means of abeveled gear wheel 13, on each end of the shaft 12, which meshes with abeveled gear wheel 14 on one end of a short shaft 15 having its bearingsin detachable brackets 16, mounted on the extension plate 7, the otherend of shaft 15 having a beveled gear wheel 17 meshing with a beveledgear wheel 17 on the end of a short shaft 18, mounted in the projection8, of the plate 6, the other end of shaft 18 being provided with atoothed pinion wheel 19, which meshes with a toothed wheel mounted onthe shaft 2 and driving wheel 1 and inclosed between the wheel 1 and theplate 6. It will be seen that by means of this construction motion fromthe driving wheels 1 will be directly transmitted to the shaft 12 of thecutter, with a movement which will furnish the necessary power andvelocity for operating the cutters 11. Furthermore, the gear mechanismconnecting each driving wheel 1 with the shaft 12 of the cutters isinclosed by a casing 2O secured by straps and bolts 21 to the plate 6and extension plate 7.

It will be seen that the operating mechanism is suitably covered withoutoccupying much space.

The lawn-mower is operated by means of a suitable handle 22, connectedby curved metallic strips 23 secured to the plates 6.

The lawn-mower is further provided with a guide roller 24 which islocated beneath the extensions 7 and between the forward end of themachine and the driving wheels. The roller 24 is mounted atl each end ona plate 25 hinged to extension plates 7, and adjustable thereon by meansof a clamping pin 26 projecting through a curved slot 27 in the plate 25and engaging an eXtension 7. By this means the forward end of themachine may be raised and lowered to adjust the distance of the cuttersfrom the ground.

It will be seen that by means of the construction herein shown anddescribed an improved lawn mower is provided the mechanism of whichoccupies very little room and at the same time affords the necessarydriving power for operating the cutter and which is light and durable.

I-Iaving described the invention I claim:

A lawn-mower consisting of a rotary shaft, a driving wheel mounted oneach end of said shaft and consisting of a disk with an annular flangehaving a toothed periphery, a disk located within said annular flangeand forming with the wheel a casing and having a forward extension witha stub bearing7 a cutter shaft and cutters, said cutter shaft having itsbearing in said stub bearing of said extension and having a beveled gearWheel at each end, a toothed Wheel on each end of the rotary shaft andsecured to and located Within the driving Wheel, a pinion Wheel meshingwith said toothed Wheel and located Within the driving Wheel, a shaftprojecting from said pinion Wheel and having a beveled gear Wheel on itsother end, a shaft mounted in detachable bearings on the extension andhaving a beveled gear Wheel at each end, one of which meshes with thegear Wheel at the end of the cutter shaft and the other With the gearWheel at the end of the pinion shaft, a detachable, oblong casinginclosing said beveled gear Wheel mechanism, a transverse rollerextending beneath the extensions and between the driving Wheels andcutters and a triangular plate pivoted at its apex to the side of eachextension and pivotally connected at its loiver corner to one end ofsaid roller, said plates each having a curved slot in its outer end anda clamping adjusting pin located in the extension and projecting throughsaid slot.

In testimony whereof I hereunto affix my signature in presence of tWoWitnesses.
